CVE-2003-1388 1 Opera 1 Opera Browser 2023-12-10 9.3 HIGH N/A
Buffer overflow in Opera 7.02 Build 2668 allows remote attackers to crash Opera via a long HTTP request ending in a .ZIP extension.
CVE-2003-0593 1 Opera 1 Opera Browser 2023-12-10 7.5 HIGH N/A
Opera allows remote attackers to bypass intended cookie access restrictions on a web application via "%2e%2e" (encoded dot dot) directory traversal sequences in a URL, which causes Opera to send the cookie outside the specified URL subsets, e.g. to a vulnerable application that runs on the same server as the target application.
CVE-2004-1489 1 Opera 1 Opera Browser 2023-12-10 2.6 LOW N/A
Opera 7.54 and earlier does not properly limit an applet's access to internal Java packages from Sun, which allows remote attackers to gain sensitive information, such as user names and the installation directory.
CVE-2003-0870 1 Opera 1 Opera Browser 2023-12-10 7.5 HIGH N/A
Heap-based buffer overflow in Opera 7.11 and 7.20 allows remote attackers to execute arbitrary code via an HREF with a large number of escaped characters in the server name.
CVE-2003-1420 1 Opera 1 Opera Browser 2023-12-10 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Opera 6.0 through 7.0 with automatic redirection disabled allows remote attackers to inject arbitrary web script or HTML via the HTTP Location header.
CVE-2003-1387 1 Opera 1 Opera Browser 2023-12-10 7.5 HIGH N/A
Buffer overflow in Opera 6.05 and 6.06, and possibly other versions, allows remote attackers to execute arbitrary code via a URL with a long username.
CVE-2004-2083 1 Opera 1 Opera Browser 2023-12-10 2.6 LOW N/A
Opera Web Browser 7.0 through 7.23 allows remote attackers to trick users into executing a malicious file by embedding a CLSID in the file name, which causes the malicious file to appear as a trusted file type, aka "File Download Extension Spoofing."
CVE-2004-1490 1 Opera 1 Opera Browser 2023-12-10 2.6 LOW N/A
Opera 7.54 and earlier allows remote attackers to spoof file types in the download dialog via dots and non-breaking spaces (ASCII character code 160) in the (1) Content-Disposition or (2) Content-Type headers.
CVE-2004-0537 1 Opera 1 Opera Browser 2023-12-10 5.0 MEDIUM N/A
Opera 7.50 and earlier allows remote web sites to provide a "Shortcut Icon" (favicon) that is wider than expected, which could allow the web sites to spoof a trusted domain and facilitate phishing attacks using a wide icon and extra spaces.
CVE-2004-1615 1 Opera 1 Opera Browser 2023-12-10 2.6 LOW N/A
Opera allows remote attackers to cause a denial of service (invalid memory reference and application crash) via a web page or HTML email that contains a TBODY tag with a large COL SPAN value, as demonstrated by mangleme.
CVE-2003-1561 1 Opera 1 Opera 2023-12-10 4.3 MEDIUM N/A
Opera, probably before 7.50, sends Referer headers containing https:// URLs in requests for http:// URLs, which allows remote attackers to obtain potentially sensitive information by reading Referer log data.
